Configuring the PoS Module

Basic PoS Module Configuration Information

This section uses several typical usage and configuration schemes to provide a brief
overview of the PoS module configuration process as a general context for the detailed
command description sections that follow.

Default PoS Module Configurations

When the BlackDiamond 6800 series switch is powered on, the ExtremeWare software
determines which slots are occupied by I/O modules, determines whether it has a
configuration for each module, and generates a default configuration for each slot that
is occupied by an I/O module that has not yet been configured. The default
configuration is the minimal set of configuration parameter settings that will allow the
I/O module and its ports to function.
For the PoS modules, the default configuration depends on whether the module is an
OC-3 module (P3cSi or P3cMi) or an OC-12 module (P12cSi or P12cMi). The OC-3
modules have some port-pairing considerations that affect configuration (see "PoS Port
Configuration and Default VLAN Assignments" on page 3-3). In either case, the default
configuration on the PoS module is for bridging (see "Default Configuration: Bridging
Over PoS Ports" on page 3-3), with the Bridging Control Protocol (BCP) enabled, so that
the module's ports are brought up as members of the default VLAN and traffic is
bridged between all ports in the VLAN. The default configuration includes values for
the configurable SONET link parameters.
To perform routing over PoS ports using the IP Control Protocol (IPCP), or to take
advantage of other features and capabilities, such as providing redundancy over the
tributary links of the SONET network using Automatic Protection Switching (APS), you
will need to perform additional configuration tasks. For examples of how to extend the
configuration, see "Routing Over PoS Ports" on page 3-6 and "Automatic Protection
Switching" on page 3-7.
